I don’t know how they do it in the U.S. but Tom is right when it comes to Israel. At least where one rabbi is concerned:
Exactly one year ago, an investigating reporter pretended to be looking into becoming a baby dick mutilator and the rabbi not only told him, but actually took him to practice on minority babies.
With nothing more than cursory instructions outside, he was told to practice on a live baby.
After refusing to perform the surgery and asking about what just happened, the rabbi said to him: ‘they’re cannon fodder’. Literally that phrase in Hebrew.

That rabbi is now applying to the position of chief rabbi for a medium sized city in Israel.
